1 Running ACC on Systems with
Multiple ACC Cards Installed
The following HP-UX kernel parameters may need to be modified if your system has a large
number of ACC cards installed.
•
zcom_mem_size
• semmni
• semmnu
zcom_mem_size
See the section “ZCOM_MEM_SIZE” in Appendix B, “Tuning and Sizing” of the ACC
Installation and Configuration Guide for information on how to adjust the value of
zcom_mem_size .
semmni and semmnu
The ACC ZCOM subsystem requires five semaphores plus one semaphore for each ACC card
and the associated semaphore undo (semnu) structures. You may need to increase the values
of the configurable parameters semnu and semmni if zmasterd exits without logging a
message (and the ZCOM startup fails) or if any of the following messages are seen in the
ZCOM log file:
hh:mm:ss zmon 295 Download get semaphore failed error: No space left on device
hh:mm:ss zmon 290 Get zmon semaphore failure, error: No space left on device
hh:mm:ss zmlog 018 Get zmlog semaphore failed: No space left on device
hh:mm:ss pcapt 012 Get pcapture semaphore failed: No space left on device
